Belkin has expanded its portfolio of charging accessories with the launch of the UltraCharge Pro Laptop Power Bank 25K. Designed for professionals, travelers, students, and power users, the new portable battery combines a large-capacity battery, high-speed charging capabilities, and a built-in USB-C cable in a compact package.
The power bank has officially debuted in China and is currently available through JD.com at an introductory price of 529 yuan (approximately $78). With support for up to 140W output and the ability to charge multiple devices simultaneously, Belkin is targeting users who need reliable power on the go.
Belkin UltraCharge Pro Laptop Power Bank 25K Features
Large 25,000mAh Capacity for Extended Usage
At the core of the UltraCharge Pro is a substantial 25,000mAh battery designed to keep laptops, tablets, smartphones, and other portable electronics running throughout the day.
Despite offering such a large battery capacity, the device remains compliant with standard airline carry-on regulations, making it suitable for frequent travelers who need dependable backup power during flights and long journeys.
Whether you’re working remotely, attending meetings, or traveling internationally, the power bank offers enough capacity to significantly extend the battery life of compatible devices.
Built-In USB-C Cable Adds Convenience
One of the most practical features of the UltraCharge Pro is its integrated braided USB-C charging cable. This design eliminates the need to carry a separate cable, reducing clutter and making the power bank more convenient for everyday use.
Built-in cables often raise durability concerns, but Belkin claims it has engineered the cable for long-term reliability. According to the company, the braided cable has been tested to withstand more than 3,500 bends and over 10,000 connection cycles.
This durability-focused approach makes the integrated cable a useful addition rather than a potential weak point.
High-Speed 140W Power Delivery
Performance is where the UltraCharge Pro truly stands out. The power bank supports up to 140W output through either the built-in USB-C cable or the dedicated USB-C port when used individually.
This level of power output makes the device capable of charging power-hungry laptops, including professional workstations and high-performance notebooks.
Belkin states that the 140W charging capability can recharge a 14-inch MacBook Pro equipped with an M5 Pro chip to 50% battery capacity in approximately 28 minutes under supported conditions.
Multiple Ports for Simultaneous Charging
The UltraCharge Pro offers three charging outputs, allowing users to power multiple devices at the same time.
Available ports include:
- Built-in braided USB-C cable
- USB-C port
- USB-A port
The USB-A port supports up to 18W charging output, while the USB-C connections provide significantly higher power for modern devices.
This flexible setup allows users to charge a laptop, smartphone, and wireless accessories simultaneously without needing additional adapters.
Intelligent Power Distribution
To ensure efficient charging across multiple devices, Belkin has equipped the power bank with AVS (Adjustable Voltage Supply) and PPS charging technologies.
These systems automatically manage voltage levels, reduce heat generation, and optimize power delivery depending on connected devices.
Charging configurations include:
Dual Device Charging
- USB-C: Up to 140W
- USB-A: Up to 18W
- Combined Output: Up to 158W
Triple Device Charging
- Built-in USB-C: 70W
- USB-C Port: 70W
- USB-A Port: 18W
- Combined Output: Up to 158W
This intelligent distribution system ensures stable performance even when charging multiple devices simultaneously.
Fast Recharge for the Power Bank Itself
A large battery is only useful if it can be recharged efficiently. To address this, Belkin supports up to 90W USB-C input for refilling the power bank.
The high-speed input significantly reduces downtime and helps users get back to full capacity much faster compared to traditional power banks with lower input ratings.
For professionals who rely on portable power daily, this feature can be particularly valuable.
Travel-Friendly Design and Display
Although it houses a sizable battery, the UltraCharge Pro maintains a relatively compact profile.
The power bank measures:
- 164mm × 89mm × 26mm
It weighs approximately 581 grams and features rounded edges that make it easier to carry inside laptop bags, backpacks, or travel organizers.
Belkin has also included an integrated LED display that provides real-time information about battery percentage and charging status. This allows users to monitor remaining power at a glance and plan charging sessions more effectively.
The device is available in three color options:
- Black
- White
- Sand
Advanced Safety Features
Safety remains a major focus for high-capacity power banks, especially those capable of delivering laptop-level charging speeds.
Belkin has incorporated multiple layers of protection into the UltraCharge Pro, including:
- Dual smart protection chips
- Real-time temperature monitoring
- Over-voltage protection
- Over-current protection
- Flame-retardant enclosure
These safeguards help protect both the power bank and connected devices during charging.
Certified for Global Standards
The UltraCharge Pro has received several important certifications that demonstrate compliance with safety and quality requirements.
These certifications include:
- China 3C Certification
- CE Certification
- KC Certification
- PSE Certification
The broad certification coverage provides additional confidence for users who intend to use the power bank across different regions and environments.
